“…In the present study using a modified bin of 6 replicates and each containing four kg of food waste we could harvest an average of 0.567 kg of BSF larvae/bin. Gligorescu et al (2020) used about 190 kg of food waste to produce 79 kg of BSF larvae by adding young BSF larvae, produced by artificial breeding of BSF to the waste. But in our study natural breeding was opted to allow the larvae to develop in the waste without artificial breeding, which might be the reason for lesser production.…”

Waste management with limited resource input under minimum space is the need of the hour. Black Soldier Fly (BSF)/Hermetia illucens is a fly prevailing and flourishing in our tropical climatic condition and is a miracle insect since it can solve a multitude of global problems like waste management, animal feed production and energy production. This fly is highly reputed in converting low quality biomasses in to high protein, high energy larvae meal. In this study we are assessing the quantity of BSF larvae produced from food waste and the waste reduction efficiency of the BSF larvae. Four kilograms of food waste was kept in a modified bin with 6 replicates and the development of the larvae was through natural breeding. The study revealed that from the above said quantity, an average of 0.567kg of BSF larvae can be produced per bin and average waste reduction efficiency was 73.81%.

“…In recent years, economic interest in this species has grown yielding abundant scientific literature on its behavior, rearing, nutritional value, and industrial applications [164,[168][169][170][171][172][173]. According to current knowledge, no viruses have been reported in this species, either at the larval stage or in the adult, despite it being a scavenger and its life cycle being associated with polluted environments [174].…”

A Systematic Review on Viruses in Mass-Reared Edible Insect Species

Edible insects are expected to become an important nutrient source for animals and humans in the Western world in the near future. Only a few studies on viruses in edible insects with potential for industrial rearing have been published and concern only some edible insect species. Viral pathogens that can infect insects could be non-pathogenic, or pathogenic to the insects themselves, or to humans and animals. The objective of this systematic review is to provide an overview of the viruses detected in edible insects currently considered for use in food and/or feed in the European Union or appropriate for mass rearing, and to collect information on clinical symptoms in insects and on the vector role of insects themselves. Many different virus species have been detected in edible insect species showing promise for mass production systems. These viruses could be a risk for mass insect rearing systems causing acute high mortality, a drastic decline in growth in juvenile stages and in the reproductive performance of adults. Furthermore, some viruses could pose a risk to human and animal health where insects are used for food and feed.

“…There is relatively little data on the most suitable conditions for the maintenance of H. illucens breeders, and on specific aspects related to the growth and development of the species, knowledge that is essential for the development of efficient technologies for the valorization of the species [ 50 ]. The justified interest for the industrial growth of H. illucens [ 51 , 52 ] also implies mastering the fine details related to the species’ reproductive behavior and of the factors with significant impact on this process [ 53 , 54 ].…”

The industrial rearing of Hermetia illucens offers sustainable solutions to the acute challenges of modern society associated with the accumulation of increasing amounts of organic waste, the substantial reduction of natural ocean fish stocks, and the imminent food crisis. Detailed knowledge of the reproductive particularities and reproductive behavior of the species is essential for increasing the efficiency of the breeding technology. This study aimed to identify the affinity shown by females regarding the size of the oviposition slots (1, 2, 3, 4 and 5 mm), the vertical distribution of the ovipositing rate, and the influence of the substrate’s moisture on ovipositing behavior (dry matter/water: 1:0.5; 1:1; 1:1.5; 1:2). Over 90% of females oviposited in the 1-, 2- and 3-mm slots, with most of the eggs (58.57%) being oviposited in the 1-mm slots. There was a positive correlation between the size of the oviposition slots and the average weight of the clutches (r = 0.985). The vertical distribution of ovipositing followed a fluctuating trend, with a tendency to oviposit closer to the attractive substrate. The females avoided ovipositing close to substrates with low humidity (1:0.5); indeed, only 6.8% oviposited under these conditions, the differences being significant compared to substrates with higher humidity (p < 0.001). The vast majority of females (43.2%) oviposited on substrates with an average humidity of 1:1 (p < 0.001). These results provide new insights into the ovipositing behavior of H. illucens, which allow for a differentiated harvest of large-sized clutches, providing practical applications with significant impact on the economic efficiency of the species’ industrial growth technology.
